I'm using iTextSharp (iTextSharp.text.pdf.PdfStamper) to add thousands of link to an existing PDF file to create a new file.
The problem is that the created file is huge (for example, original size is 20m, but the created file size is 500m). I analyzed it with Acrobat Pro, it shows 90% of that file was occupied by "document overhead". I don't know what it is, nor why iTextSharp includes that in the file.

Is it possible to make iTextSharp create the new file without "document overhead"? or how can I get rid of the "document overhead" from the PDF file?

Can you provide a short example of code that shows this? Also, what version of iTextSharp are you using? – Chris Haas Jun 23 '14 at 19:50
Thanks Chris, I'm using iTextSharp 4.5.5.0 – zhen Jun 23 '14 at 20:26

Are you sure of that version number? 4.1.6 was the last official version before jumping to 5. – Chris Haas Jun 23 '14 at 20:29
Very sorry about that, I'm using iTextSharp 5.4.5.0 – zhen Jun 23 '14 at 22:28

Can you share a sample PDF with overhead? (Maybe not the 500MB file, though...) And can you post the pivotal code? – mkl Jun 24 '14 at 07:28
